目前在模擬電路的時候,hspice顯示出* E3 P$ ]! q( l) m ?, D
**error** number of iteration exceeds min(7000, 20*itl1)= 7000 in pseudo
m1 u( E0 A9 p/ n9 F tran process (converge=1 process). Usually this happens when the' ^( }+ `0 M$ k
models are discontinous, or there are uninitialized bi-stable cells
$ U- c3 l1 `$ T G; _2 w (flip-flop) in the circuit. By setting options dcon=-1 and converge=-1
3 P$ d" g1 d1 |& ~ you can disable auto convergence process. Retry the run, non-convergence
: X3 c/ n% K/ V' O diagnostics will provide useful information about the nodes and devices; S7 s8 V- Y3 T/ J/ Q: |6 W
which can be used to work around the non-convergence problems.

而我的設定為- ~ L0 H1 W( g7 f0 L* a& }
